About

This Pre-Algebra Basics course will take place over four one-hour sessions, students will review and practice topics such as factors, ratios & rates, exponents, variables & expressions, and basic equations. The sessions will include step-by-step explanations, guided practice, and time for questions to help students feel more confident and comfortable with pre-algebra concepts. This session is great for students who want extra support, a refresher, or a confidence boost in math. Learners will need to bring a notebook or loose-leaf paper, a pencil, and a basic calculator (optional, but helpful)
